I think Mark Steyn got it right:
And so the Gulf spill was an irritation, but he dutifully went through the motions of flying in to be photographed looking presidentially concerned. As he wearily explained to Matt Lauer, “I was meeting with fishermen down there, standing in the rain, talking . . . ” Good grief, what more do you people want? Alas, he’s not a good enough actor to fake it. So the more desperately he butches up the rhetoric — “Plug the damn hole!”; “I know whose ass to kick” — the more pathetically unconvincing it all sounds.
I think he's got the Prez pegged. Read every bit of that bad puppy.
